That's incorrect, there are non-EU countries using the Euro too like Andorra.
From a legal perspective, what's stopping any country from adopting the Euro? In theory they could continuously purchase euro with their currency and limit national currency use. Obviously there are downsides to the country doing it but is there anything legally stopping them (in an international law sense)?
That combined with one or two more arguments and you have yourself and abstaining country.
